Prenatal Fluoride Exposure Lowers Babies’ Intelligence, Study Shows

Pregnant women’s urine fluoride levels are linked to lower intelligence in their offspring, according to a US government-sponsored study published in Environmental Health Perspectives (September 2017), and at levels commonly found in US adults.

Fluoridation lobbyists cavalierly dismissed this study because it was conducted on women from Mexico which makes it irrelevant to the US, they claim.  However, urine fluoride levels in healthy US adults in US fluoridated areas are similar and is a measure of one's total fluoride intake from all sources. 

The lead researcher, Dr. Howard Hu, also disagrees with their assessment. He is quoted in the media as saying “This is a very rigorous epidemiology study. You just can’t deny it. It’s directly related to whether fluoride is a risk for the neurodevelopment of children. So, to say it has no relevance to the folks in the US, seems disingenuous.”

Most US water suppliers add unnecessary fluoride chemicals into public water supplies in a failed attempt to reduce tooth decay for political not scientific reasons.

Hu says the study “also suggests that the prenatal nervous system may be more sensitive to fluoride compared to that of school-aged children.”

This new careful investigation, by respected researchers from respected institutions and published in a respected peer-reviewed journal, adds to a frightening trend.  Over 300  studies  now link fluoride to neurotoxic effects – 50 of them human – over 20 at fluoride levels allowed in US water supplies. Taken together, with this new study added, the evidence is now very strong that fluoride exposures common in the USA is causing IQ loss in at least some children.

A New Zealand study (Broadbent, et al) is often touted as proof fluoride is not neurotoxic.  However, that study showed no difference in total fluoride intake between children in fluoridated and nonfluoridated areas since most of the children in nonfluoridated areas were given fluoride supplements.

According to the Fluoride Action Network (FAN), “The loss of IQ is very large.  The child of a mother who was drinking 1 ppm fluoride water would be predicted to have 5 to 6 IQ points lower than if the mother had drunk water with close to zero fluoride in it… Such a drop of IQ in the whole population would half the number of very bright children (IQ greater than 130) and double the number of mentally handicapped (IQ less than 70).”

The researchers adjusted for a wide range of other factors including lead, mercury, socio-economic status, smoking, alcohol use, and health problems during pregnancy.

Urine fluoride is a good indicator of total fluoride intake from all sources. When drinking water is the dominant source of fluoride, urine fluoride and water fluoride are usually about the same So, the average urine fluoride level in this study of 0.9 mg/L implies that women were ingesting the same amount of fluoride as women drinking water with 0.9 mg/L fluoride, according to FAN.

Up until 2011, government agencies advised artificially fluoridating water up to 1.2 mg/L.  Because of the growing dental fluorosis epidemic, they revised it downward to 0.7 mg/L.  But it’s just a recommendation. Not all water suppliers comply. Also, many US communities are served naturally fluoridated water up to 4 mg/L.

Fluoridated water is not the only fluoride source that adds to the bodies total fluoride burden.  Virtually all foods and beverages have some fluoride. Fluoride is absorbed into the bloodstream from topical application of fluoridated dental products and is a component of air pollution.

Dr. Leonardo Trasande, a pediatrician who studies environmental exposures and health problems at New York University Langone Health  said to Newsweek: “This is a very well-conducted study, and it raises serious concerns about fluoride supplementation in water. These new insights raise concerns that the prenatal period may be highly vulnerable and may require additional reconsideration.” 

Fluoridation lobbyists, such as the American Dental Association, the American Fluoridation Society and the Children’s Dental Health Project (sponsored by the American Academy of Pediatrics) erroneous claim that

Mexican mothers had fluoride exposures higher than found in the USA and therefore the study isn’t applicable to American women.  They fail to understand the urine levels come from a mix of sources.  What’s relevant is that the fluoride levels found in Mexican mothers urine is similar to that found in Americans regardless of the sources of exposure.

After fluoride gets into the body and can be measured in the urine, as was done in this study, it is immaterial what the original source of that fluoride is.  The fluoride may have come from fluoridated water, fluoridated salt, swallowed toothpaste, fluoride supplements,  dental office fluoride treatments and/or air pollution.  Once fluoride  is ingested or absorbed into the bloodstream, it is all the same in terms of toxic effects on the fetus.  The developing brain in the fetus can't tell which source the fluoride came from.

This study was performed by respected leading researchers in environmental neurotoxins.  It was funded by $3 million in grants from the US National Institute of Environmental Health Sciences. It was published in the premier journal for environmental health after undergoing peer-review. 

Understandably, this study cuts to the heart of the dental profession's support of fluoride to combat dental decay.  But rather than a knee-jerk reaction to deny the importance of this study in the interests of teeth, perhaps dentists should take a more holistic perspective and consider the entire child, including his cognitive development.  How many IQ points loss would you consider is worth one cavity prevented???

Dentists Responsible for Tooth Decay Epidemic?

• Fluoridation: A Failed Tooth Decay Preventive, Federal Data Shows
• Cavity Rates Unchanged
• Dental Fluorosis Up 600%
• Safety Still Doubted
• Is Organized Dentistry, Compared to ISIS and the NRA, to Blame?
• Dental Therapists, Not Fluoridation, Reduces Oral Health Disparities 
• Politics, Not Science, Keeps Fluoridation Afloat

After 72 years of fluoridation, reaching 2/3 of Americans, promising to substantially reduce tooth decay, especially in poor children, the American Journal of Public Health (2017) reports “Despite significant financial, training, and program investments, US children’s caries experience and inequities continued to increase over the last 20 years.”

 

Children are fluoride-overdosed while oral-health-disparities between poor and non-poor increase. “America's shockingly poor dental care system,” is profiled in the Yakima Herald.

The silent oral-health epidemic, declared in 2000 by US Surgeon General David Satcher, persists today, he says.

For example: 2001 statistics show that tooth decay doubled after fluoridation was mandated in Kentucky in 1977

in 2016, cavities in Kentucky children increased again despite more oral health education, dental visits, sealants,

fluoride varnish and supplements on top of water fluoridation as the below graphic depicts.

By avoiding the real problem - lack of dentists who care to treat poor people - has organized dentistry created this dental health epidemic the US faces today?

Fluoridation, an outdated 1945 concept, predicted only 10% would suffer mild dental fluorosis (white-flecked teeth). However, 58% of adolescents are now afflicted - some with more severe fluorosis (stained, pitted teeth) without benefit of less tooth decay.  Dentists are profiting from covering dental fluorosis.

The Journal of the American Dental Association (Dye 2017) reports,

65% of poor 6-8 year-olds and 12-15 year-olds have cavities in their primary and permanent teeth, respectively.

Dye reports: “The prevalence of pediatric caries in the United States has remained consistent for the past 3 decades.” 

"… there has been little improvement in preventing caries initiation," said Dye.

Is organized dentistry, leading fluoridation promoters, to blame?  They wrote in December 2016, 

"the ADA will need to increase efforts in communities not only where fluoridation is challenged but increase efforts to assist members in identifying and initiating fluoridation efforts in those communities where fluoridation might be successfully implemented." (This link has been removed from public view after this was published.) 

80% of dentists refuse government-sponsored dental insurance (i.e. Medicaid and CHIP)  They prefer to treat the water of but not the teeth of low-income folks.  Fluoridation gives the illusion that organized dentistry cares about the poor folks who aren't welcomed in their dental chairs.

Legislators are often intimidated by fluoridation-promoting dentists who threaten to unseat them if they vote against fluoridation as happened in Pinellas County, Florida.  Too many legislators prefer to keep their jobs than protect their constituents.

Organized dentistry is possibly protecting its political viability by supporting fluoridation. But are the American people protected? Researchers report fluoridation safety doubts persist

Some say to follow the money.  In fact,  organized dentistry misinformed and manipulated California legislators to mandate fluoridation in 1995 . And they continue to thwart  perceived threats to their lucrative monopoly as occurred when  the Massachusetts' Governor attempted to legalize Dental Therapists in the state but was dropped due to strong opposition by dentists.

 

Reason Magazine reports “The over-the-top intimidation tactics of the ADA [American Dental Association] and its shiny-toothed shock troops,” contributed to high healthcare costs. A lawmaker is quoted as saying “I put their power right up there with the NRA.” 

The Washington Post (“The unexpected political power of dentists”) quoted a Harvard dentist comparing the ADA to ISIS.

In July 2017, a California newspaper reports the "Dental lobby prevails again in Legislature," by blocking legislation intending to save children's lives.

Free once-a-year “pop-up” dental clinics “fail to relieve the suffering of marginalized people but also can produce it,” according to a dissertation by Raskin. 

Raskin explains extractions are routine and “incentivized” instead of preventive or restorative care. Dentist volunteerism declined; patients are turned away.

Oral health issues costs $6 billion in lost productivity yearly. Emergency department oral pain visits cost $2 billion yearly and contribute to the opioid-addiction epidemic.

Organized dentistry has priced low-income Americans out of dental care but spent millions of dollars unsuccessfully trying to thwart Dental Therapists from working in rural Alaska where dentists refused to work or live and where people were pulling out their own teeth.  They claimed patients would get substandard care; but 11 years later reports show Dental Therapists are successful.  For example:

-- more children and adults received preventive care

-- Fewer children under age 3 had extractions of the front four teeth
-- Fewer adults ages 18 and older had  tooth extractions

In 2008, the New York Times profiled the political clout of the New York State Dental Association.

July 2017, the New York Post reported that that NYS Dentist PAC donated $4M to political campaigns in 2010 and “the mint from the dentist’s chair has paid off – the trade group has blocked legislation in the statehouse that could spur competition and hurt business.”

Evidence that fluoridation failed New York State is here and here

.People need to take back their water systems from special interest groups.

Despite growing evidence that fluoridation is a failed concept, the American Dental Association and its constituent groups are aggressively pursing increased fluoridation throughout the nation without discerning or caring that our children are already fluoride overdosed.. Are they serving the public or the political viability of organized dentistry?
